摘　　要：对重庆秀山锰矿废弃地进行生态环境现状实地调查和采样分析,记录秀山锰矿区废弃地上自然定居的植物,并采集巴天酸模、铁杆蒿、商陆、土荆芥、小白酒菊、艾、扛板归、狗牙根等8种主要优势植物样本.对8种主要优势植物的Mn等重金属元素含量进行检测分析,采用生物转移系数(BTF)和生物富集系数(BAF)两个指标进行其生物学特性研究,确定巴天酸模、铁杆蒿、商陆三种植物对土壤中Mn元素的生物转移和富集作用强,筛选出该三种植物适宜作为锰矿区废弃地自然生态恢复的先锋植物,并提出秀山锰矿废弃地植被恢复技术措施的建议.By field investigation and sampling analysis of the ecological environment of Xiushan manganese mine wasteland,all kinds of resident plants were recorded and eight of them as dominant plants had been screened out,which were Rumex patientia,Artemisia sacrorum,Phytolacca acinosa,Chenopodium ambrosioides,Conyza canadnsis,Artemisia argyi,Polygonum perfoliatum and Cynodon dactylon.The contents of metal elements in these plants such as manganese were detected and their biological characteristics were assessed using biological transfer factor（BTF） and biological concentration factor（BAF）.It was proved that Rumex patientia Linn,Artemisia sacrorum Ledeb and Phytolacca acinosa had the strongest biological transfer and bioconcentration effects.Thus,these three kinds of plants were chosen as dominant species for ecological restoration at the manganese mine wasteland,and the relevant restoration techniques were proposed.
